'Patented Oct. 27, 1931 UNITED STATES PATENT OFFICE CHAIR Applicationi'iled March 21, 1930. Serial No. 437,822.

This invention relates to chairs and more especially to recliningchairs.

Itis an object of the invention to provide a chair having a yieldinglyrestrained movable back with which is associated a movably supportedseat so mounted that the weight oit' the occupant of the chairconstitutes a supplemental means for resisting the backward movement ofthe chair-back when the occupant presses thereagains't.

Another object is to provide a chair the seat and back portions of whichcan be removed readily from the frame for convenience in shipping andstoring and also to i'acilitate cleaning, upholstering, or repairing theparts.

A still further object is to provide a chair which is of simpleconstruction and will not readily get out of order.

With the foregoing and other objects in View which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed may be made within thescope of what is claimed without departing from the spirit of theinvention.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings Figure 1 is a central vertical section through thechair.

Figure 2 is a bottom plan view, parts being broken away and the Jfrontlegs removed.

Figure 3 is a section on line 3 3 Figure 1.

Figure 4 is a section through a portion of the chair showing therelative positions of the parts when the back is pressed backwardly toan inclined position.

Figure 5 is a view partly in section and partly in elevation showingportions of the near side of the back and seat trames at theirco-operating ends.

Figure 6 is a view similar to Figure 4 showing the relative positions ofthe back and the chair frames after the seat frame has been removed andthe back fra-me has been swung to released position.

Figure 7 is a section on line 7 7 Figure 1.

Figure 8 is a perspective view of the cooperating rods of the backrestraining mechanism.

Figure 9 is a perspective view of one of the bearing blocks forsupporting the back frame.

Figure 10 is a perspective view of a bracket for supporting thecross-bar.

Figure 1l is a detail view of a modified 4 form of bearing member whichcan be used on the chair.

Referring to the figures by characters of reference 1 designates a chairframe supported at its front corners by legs 2 and, at its rear cornersby legs 3. If desired, and shown in the drawings, the legs 3 can be madeintegral with standards 4 supporting the back ends of the chair arms 5.The front portions of these arms can be supported by standards 6 securedto the sides oit' the frame. t is to be understood, however, that anydesired construction of the frame and arms can be used.

Secured to the inner sides of the standards 4 close to but above therear portion of frame 1 are bearing blocks 7 each of which has a slot orrecess 8 extending downwardly thereinto. To the inner sides of the sidesof frame 1 are fastened brackets 9, each of which has an oifset slottedtongue 10.

Extending transversely of frame 1 near its front end is a rod 11 theends of which are suitably seated in the sides of the frame as shown at12 or are otherwise supported. Parallel with this rod and adjacent tothe center of the frame 1 is a cross-bar 13 having pins 14 projectingfrom its ends and removably seated in the slotted tongues 10 of brackets9. This rod has an opening 15 in which can be seated a guide sleeve 16.

The back frame of the chair has been indicated at 17 and is providedabove its lower end with a transverse rod 18 the ends of which projectlaterally fro-m the back frame and are removablyT seated in the blocks7. This arrangement is shown clearly in Figures 3 and 7. rlhe lower endsof the sides of frame l? are connected by a rod 19 and theseends areadapted to bear backwardly against the back of the chair frame 1 whenthe backframe 17 is in its normal or fully raised position. This hasbeen illustrated clearly in Figure 1."v AObviously the back frame can bereinforced by cross-strips 20 located wherever desired.

n For the purpose of maintaining the back frame17 knormally yin-theposition illustrated in Figure 1, a rod 21 is slidably mounted in thesleeve 15. This rod has a forked head 22 which straddles the' rod 19. Acoiled spring 23 is mounted lon the rod and bears at one end againsthead 22'while its other end bears against the bar 13er a flange 24integral with sleeve 15. Thus it will be seen that spring 23 will beheldnormally funder compression yso` that the lower endof frame. y17

is normally pressed against the .back end of:

framel. When frame 17 is pressed backvWardly at itsupper end 4the rod19will push P l Vto hold the-ends ofthe-rod against accidental against'head 22 so as to further kcompress spring V23 andy if there is nothingto prevent it, the back frame 17 can beswung rearwardly andd-ownwardlyito move rod -19 past itsdead center, as shown in Figure 6 sothat fra-nie '17, rod21, bar 13,.and spring 23 can be removed as will beobvious.

` The seat frame has beenqindicated ats25and is of such size as to litloosely between the sides kof frame 1 yand between the front ofsaid'frame and the lower portion of frame 17 `A transverse groove 26 isprovided inthe bottom-ofthe frame 25 near its front-,end and is adaptedto receiverod 1=1 so that the front portion .fof seat frame A25 willthus be sup- ,k ported. Tongues 27 are extended rearwardly fromtheseat'frame 25 and to each of these tongues :issecured a bearing plate28 the free end portion of which'is offset to form a small yoke 29adapted normally to straddle rod 19 asvshownyfor example, in Figures 1and l2. Each platecan befurtheroffset transversely to iprovidefagrooveBOfadapted-to receive the rod 19 whenfthe back frame `17 lis swungrearwardly tothe limit of its movement as shown in Figures 4 and 5 atwhich time the lower endportions 4of the sides of frame-17 press againstthe l:rear end of frame 25. Wear buttons 31-canybe mounted on the end-offrame 25` to j receive thrusts from frame 17.

As-beforestated,spring 23 holds the frame 17 normally in the lpositionshown in Figure 1. Whenthechairis occupied the weight'of the occupantAfurther actsto restrain frame 17 IVhen'the occupant of the chairpresses backwardly against-the back of the chair the rod 19 -will swingforwardly and upwardly. This will causeV the spring 23-to be placedunder increased compression and atthe same time rod 19 will move out ofthe yoke 29 and movement of frame 17 will be limited by its contact withframe 25 or the stops 31 therelwardly to the position shown in Figure 6and theparts separated as heretofore explained. Instead of using thebearing blocks 7 the ends of the .rod 18 can Lbe seated removably inangular slots 32 formed in-theiofset inter.-`

mediateportions 33 lof plates 34 which are attachedto the standards 4.Levers y35 are ivotally connectedto these plates andserve withdrawal.from the inner ends of the slots in which the rod is seated. y

What'isclaimed is: l 'Y p f The combination with a chair frame .and across-bar removably and rotatively mounted therein, of aback-frameremovably andpivotally supported by the chair frameacrossrod carriedV.by the ,back frame below the pivot thereof,y a slidable removable`connection between the cross-rod and the bar, and yielding meanscarried by said connection for exerting a thrustagainst the rod -.tohold theiback frame normally'in a ,predetermined position,

said back frame being movable to shift lthe rod past .adead center andrelease the back frame bar, :and slidable connection for. separationandremoval fromt-hechair frame.

In testimonyfthat I claim the foregoing as myown,'I have hereto affixedmy signature. Y v JACOB D. l13A-IR.
